A cheap fix is to buy some faucet washers and use a metal screw in the center and snug it up. Only a temporary fix.This is safer than dripping gas as you drive. A very dangerous condition.Check with some radiator shops they will clean and solder the leaks and use a liquid glass liner which sets up. I think after rereading is the following.
All you are looking at is a hose available from the dealer. Don't use a piece of radiator hose it will soon get stiff from experience. You have to loosen the straps on the tank when about empty and lower the tank until you can put your hand up and install new hose. Use a stanley knife to slit the hose then remove it. Then clean before installing a new hose.Maybe all it needs is a new hose clamp.
I would put it on jackstands and try clamps first unless the hose has a hole in it.
